How to start two instances of Spyder with Python 2.7 & Python 3.4?

I had spyder installed with Python 3.4 on Windows Vista.

Today I wanted to run spyder with Python 2.7. So, went through this post & installed Python 2.7 for spyder. Now, how do I start spyder with Python 2.7 instead of the default 3.4? (I wanted to comment at the post & ask @user3058525 but could not due to reputation restriction)
